This examiner grants 27% of resolved cases

Analysis

Chia-Yi Liu works in Tech Center 3600 and Art Unit 3692, with 318 resolved cases. The allowance rate is 27.0 percent, which is quite low. The median days to allowance is 1704, indicating a long and difficult prosecution process. These metrics suggest that applicants face a challenging environment with a low probability of success and an extended timeline for reaching a final outcome.

However, interviews provide an interview lift of 21.2 percent. While the 27.0 percent baseline is low, the significant lift suggests that direct communication is a much more effective strategy than relying solely on written responses. Practitioners should prioritize interviews to resolve issues and improve their chances of success, potentially navigating the 1704-day prosecution process more effectively through direct dialogue with the examiner.
